' RECEPT'ACLE COVER OPERATOR AND LOCK Filed sept. 1. 1944 Patented Mar. 15, x 1949 UNITED STATES] PATENT oFFic-E RECEPTACLEJ COVER OPERATOR AND LOCK Carl Hilbert Carlson, Chicago, Ill;

Application Septemberl 1, 1944, Serial No. 552,336

This invention relates to improvementsl in. receptacle cover locks. andi more particularly to a garbage receptacle cover locking device which, however, is capable of application to a Variety of tapes of receptacle. covers.

One object is to provide a receptacle cover lock that may be manufactured along with the receptacle with which it isi'associated or that may be made separately and installed upon various types of receptacles after same have been in use.

A: further object is to provide. `a receptacle cover lock that is. rat and vermin proofand therefore sanitary in. use. A still further object is to provide a-,cover lock` for receptacles that is proof against tampering by unauthorized persons.

Ai still `further object is. to provide a receptacle cover lockthat is durable in use, inexpensive to manufacture, composed of few parts and not likely to get out of order, that is shielded, but one wherein the operating parts are readily accessible so that repair or replacementv when necessary may be readily made.

With theforegoing and otheryobjects in View thefnvention! consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the claim and illustrated in the accompanying drawing that forms a part of this patent, and in which- Fig. 1 is a View in perspective of a receptacle provided with a hinged cover and with the instant locking device which is not disclosed in this View but which is fully shown in the following views.

Fig. 2 is a vertical substantially central sectional view through the receptacle and cover of Fig. 1 but in open position, illustrating the cover locking mechanism.

Fig. 3 is a fragmentary sectional view similar to Fig. 2 but with the movable parts in an altered or closed position.

Fig. 4 is a view of the locking mechanism in elevation, taken on the line 4-4 of Fig. 3, and

Fig. 5 is a vertical cross sectional view through the receptacle proper, at right langles to that Shown in Fig. 2.

Like reference characters denote corresponding parts throughout the several views.

'I'he reference numeral I denotes the receptacle body provided with the usual discharge opening 2 upon opposite sides of and rising above which are the ways 3 for the sliding door 4 provided with the perforated lug 5 for engagement by the hook 6 secured thereabove to the receptacle wall by the screweye 1. The receptacle is provided also with the orice 8 having the angular metal facing 9 to which is secured the bracket I0 de- 1 Claim. (Cl. 268-74 l pending.v into the receptacle and formed or pro-- vided with a perforate ledge Il horizontally dis.- posed and extending longitudinally of said oriice.

Journaledl in bearings I2 in the side walls of.' the receptacle and extending through said brack-v et I0 is the shaft |3., the ends of said shaft being squared for engagement with the notched endof the key or handle I4 which is inserted in wall` perforations for engagement with the countersunk shaft ends. Fast-upon shaft I3 is the :pri` mary lever I5 connected by link Ito the secondary lever Il intermediate its ends, one end ofv said lever I'I being bifurcated and secured by pin I8 to bracket Ill, said lever at its opposite endi being. pivotally secured' to a primary lever. I9 pivoted to an ear 2li' depending from the inner face of. the cover 2| pivoted to ears 22,. said coverv having4 downturned anges '23 that in the closed position of said cover fit snugly about the orifice making' the receptacle rat and vermin proof.

Referringl againto'v said lever l5 same carries a spur 2'4' to which one end of a contractile spring 25' is secured that is connected to a cord 26 that.

passes about a peripherally recessed guide roller'.

21 the axis of which is secured to said bracket II), said cord then being secured to the shank 28 of a bolt 29 slidably arranged within the bolt casing 30 secured to said bracket ID and to ledge I I. The shank 28 extends through a perforation in one end of said bolt casing while the free end of said bolt is movable through a perforation at the opposite end of said casing, said shank in its movement passing between the prongs of said lever I'l and having disposed thereabout within said casing 30 the coil spring 3| one end of which abuts said bolt and the opposite the adjacent end of said casing.

In Figs. 2 and 5 lof the drawing the cover 2| is shown in wide open posi-tion, said cover having secured thereto the keeper 32 perforated for reception of the bolt 29. As :the cover is moved manually to closed position the levers I9, I'|, link I6 and lever I5 rotate shaft I3 Iand relieve tension of spring 25 and permit spring 3| to expand and urge the bolt 29 outwardly with respect to casing 3U and, as the keeper is moved into line therewith, to enter the keeper perforation and lock said cover in closed position. An effort manually to raise the cover now will fail due to the presence Iof bolt 29 in keeper 32, said keeper exerting an upward and binding pull against said bolt. The cover Ican now only be opened by applying the handle to one end of the shaft I3 lto rotate same and raise lever I5 with its connections to said cover, movement of lever l5 expanding spring 25 through the medium of cord 26 and shank 28 retracting bolt 29 against the tension Yof spring 3| to free the keeper 32 allowing the cover to be moved upwardly, the upward movement of lever I7 causing it to contact ledge Il and arrest the opening movement of said cover in substantially wide open position disclosed in Fig. 2.

A detachable shield plate 33 formed with lateral flanges secured to ledge Il and facing 9 defpends from the orice into the interior of the receptacle alongside the locking mechanism to protect same from the material received thereinto and protecting said mechanism from tampering while the cover is in-an open position, said plate flange being perforated :to receive -pins whereby to connect it to correspondingly perforated portions of said ledge, said plate being formed of resilient material, .the end flange being pressed into binding engagement with the orice facing when the plate is in operative position.

The ange 34 is disposed horizontally to lie at upon the said ledge Il when its perforations will be disposed in register with like perforations in said ledge to receive pins 35 to retain said plate in operative but readily movable position, the flange 36 formed upon one upper corner of said plate being vertically disposed and bent laterally in a position parallel with said facing at this point against which facing said ange is s-omewhat tightly pressed when flange 34 and ledge I I are in engaged relation.

What is claimed is:

In a receptacle cover lock, an oblong body hav ing ya top formed with an orifice, a cover hinged to said top at said orice movable longitudinally Iof said body, a bracket depending from said cover into said body at said orice, a rotary shaft extending transversely of said body through said bracket forwardly of the hinge-point of said cover, a ledge integral with said bracket extending longitudinally of said orifice, a lever connection between said cover and bracket passing through said orice for engagement with said ledge as said cover assumes wide open position, the ends of said lever connection disposed upon opposite sides of said rotary shafit in the Wide open cover position, a keeper carried by and d-isposed normal to said `cover and in the closed cover position disposed substantially wholly within the body, a bolt casing within the body in line with and contiguous to said keeper in the closed cover position, a sliding bolt in said Icasing for engagemenltI with said keeper, a spring within said bolt casing connecting same and said bolt for yieldingly projecting same through one end of said casing linto engagement with said keeper, a lever fast to said rotary shaft, a spur carried by said lever, a link connecting said lever and the aforesaid lever connection, Va resilient .Connection between said spur and sliding bolt, and a handle yfor removable operative engagement with said rotary shaft to transmit an opening movement to said cover.
